The notion of the grand unification of gauge interactions has been with us for over 40 years. Supersymmetry is often regarded as the savior of grand unified theories as the additional particle degrees of freedom in theory help in the unification of the gauge couplings. In addition, supersymmetry provides us with a compelling candidate for dark matter. However, supersymmetry to date, has not been discovered at the LHC. The implications of recent LHC results for supersymmetric dark matter will be discussed as well as alternatives in non-supersymmetric grand unified theories.
